POR-15 Inc. brings the powerful technology of polymeric isocyanate derivatives to the consumer rust prevention market for the first time, a technology vastly superior to competing products currently on the market.
POR-15® is easier and less expensive to apply than epoxies, since it doesn’t require mixing: and POR-15® dries to a high-gloss or semi-gloss finish just like paint, except that it cannot be scratched or peeled off.
Since POR-15® chemically bonds to metal, the underlying surface does not have to be sanded before application. As long as loose or flaking rust are removed from the surface, an application of POR-15® will not only cover up the rust and prevent it from spreading, but will also strengthen the underlying metal and seal holes by forming its own membranes.
POR-15 is a rust-preventive paint designed for application directly on rusted or seasoned metal surfaces. It dries to a rock-hard, non-porous finish that won’t chip, crack, or peel, and it prevents rust from re-occurring by protecting metal from further exposure to moisture. POR-15 is sensitive to UV light (sun) and must be topcoated before prolonged exposure to sunlight. POR-15 is cured and strengthened by exposure to moisture and will dry faster under extreme humidity, but moderate to dry atmospheric conditions are most desirable when applying this product,because extreme humidity may cause an immediate surface cure, trapping carbon dioxide gas below the surface. When this happens, bubbling may occur. Extreme humidity at the time of application may also interfere with proper adhesion of the POR-15 coating to metal because it’s almost impossible to keep metal dry under such conditions.
POR-15® is a paint-like substance which acts as a total rust inhibitor and also very effective as a metal filler. Its consistency is approximately that of paint and it has very good spreadability (one quart covers 96 square feet). POR-15® chemically bonds to rusted steel to form a rock-hard, nonporous coating that won’t crack, chip, or peel. It works by isolating metal from moisture; without moisture present, steel can’t rust. Thin, covering coats are best. Apply second coat when first coat is dry to touch with slight “finger-drag” remaining.
